I use postfix and dovecot as mail server in java application. I use virutal domain, mysql database etc. to send internal mail. If i want send mail to world i use my mail account in mail service provider. I want everybody can send outgoing mail so i set in sender_canonical ----------------------- /^.*/ mym...@isp.com ----------------------- and i set in main.cf "sender_canonical_classes = envelope_sender". My internal domain is @mydomain. This domain is ownership by my client, but my mail server isnt visible from world. I use header_check to prevent user set mail from other domains, e.g us...@xxx.com. It is fine.
I cant use generic because in this case recipient see as sender address "mym...@isp.com". It should be e.g user1@mydomain. In dovecot i use plugin quota exceeded to inform sender about no delivered mail if somebody send internal mail. My problem is that dovecot send information about no delivered messages to envelope_sender instead header from. I try force dovecot to use header from but i cant. I also write on dovecot mailing list by i didn't get answers still. I would be very greatfully if you could help me. -- View this message in context: http://postfix.1071664.n5.nabble.com/sender-canonical-maps-and-no-delivered-mails-tp64909p65348.html Sent from the Postfix Users mailing list archive at Nabble.com.
